How do I add a field in the attribute table that automatically calculates the sewer lateral depth?

What's the formula that I need to use in [Field Calculator]?

What do you mean by "[Find Calculator]"? If it is the Field Calculator then what have you tried? What is an FSN? – PolyGeo Jan 8 at 22:30
  • If you are asking how to add a field, and calculate as the difference between two others, this is pretty basic. What have you tried? See Calculate Field examples here – BERA Jan 9 at 10:18
  • @BERA I think what Lina is asking for is a field which does this automatically when a feature is created or edited. For Arc that would be the Attribute Assistant plugin. Which is fantastic but a bit of a rabbit hole. – TeddyTedTed Jan 9 at 10:44
